HOTBED.

Specification' of Letters Patent. applibaaon ined March 6, 1909.

To all whom it nza/j concern:

Be it known that AI," Grno1fu;u H. BARBOUR, of Pittsburg, Allegheny county, Pennsylvania,.havo invented a new and useful Hotbcd, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Y Figure 'l is al plan showing a portion of a double hot bed constructed and arranged in accordance with my invention' Fig. 2 is a sectional end elevation showing olie bed and a. portion of the other bed of the double hot bed shown in Eig. 1; Fig. 8 is a longi` tudinal sectional elevation on the line Hlis a detail sectional end elevation on a larger scale showing the =receiving and delivery 'sides of one of the beds of liigs. 1, 2 and 3, the connecting centralportion of this bed being broken out; Fig. 5 is a top plan, Fig. G a side elevation, Fig. 7 is an inverted bottom plan, and Fig. 8 is an end elevation showing a detail of one of the rocking plates forming part of my invent ion.

My invention relates to apparatus employed in handling metal bars, hoops and similar materials, and it more particularly relates to such apparatus employed in handling such materials while being cooled from the hot state in which they are delivered from the rolls of rolling mills inwhich such materials a re manu factured.

The object of my invention is to provide improved means for handling such materials, by which the bars or other materials are removed from the receiving table or other device on which they are delivered from the rolls or other place of supply alongside the hot bed'in position to be removed and to be shifted transversely of their length to a delivery table, to which they are transferred from the hot bed, and on which they are delivered to the shears or other place of disposal.

A further object of the invention is to provide bar handling apparatus having improved means for supporting the bars whereby damage or distortion of the. materials is prevented while being handled and to provide improved mechanism for actuating the bar-,handling appara-tus.

.ln wthe drawings 2 represents the rollers of a roller receiving table, on which the materials are delivered from the rolls of the rolling mill, alongside the hot bed or transt t i t i t t t Patented Dee'. 14, 1909. Serial No. 481,565.

fer mechanism in position to be moved across the width of the hot bed, and the rollers of a delivery table, upon which the materials are received from the hot bed and by which they are delivered to the shears or other place ofl disposal.

Mounted in suitable bearings 4 are the rocking shafts, 5, on which are the rocking arms (i, which are connected together and to a suitable operating motor (not shown) by the reciprocating rods 8. The shafts 5 are provided with the arms 9 and 10, which extend in opposite directions on the shaft. A. ball-and-socket connection 1l is formed between the ends of the arms 9 and 10, and the` vertical movable supports 12, on which are the longitudinally extending beams 13 and lll. Mounted on the longitudinally extending beams 13 and lll are the pivot supuorts Yl5 and 1G, these pivotsupports being arranged, together with the longitudina beams 123 and 14, to be. reci procated in a vertical direction when the rocking shafts 5 and the arms l and 10 are actuated through the rods S connected with the motor. The axes of the rocking shafts 5 are arranged as shown, at right angle to the axes of the rocking plates. livotally mounted in the pivot bearingson the supports 15 and 16 is a series of rows of flat, rocking plates 1T, pro vided with pivot-shafts 18 by which they are secured in place on the supports er 1 6. The opposite side or edge of the plates 17 is provided with curved lip portions 19, which engage with and slide upon the pivot shafts 18 of the adjacent rows of supporting plates.V nearest the receiving rollers Z are provided with hook portions 2l, which ar arranged so as to be below the line of feed of the materials being' delivered on the rollers 2, and which are arranged to lift and transfer the materials from the rollers 2 to the rocking plates 17 forming the supporting surfaces of the hot bed. The opposite side of the beds is provided with a series of inclined chutes 2;), on hich the materials slide when they are finally transferred from the hot bed by the, tilting operations of the rocking plates. A stop 23 is provided to hold and collect a` number of bars until such time. as the stop Q3 is actuated through the lever arm 2l and connecting rods 25, by a suitable rocking motor not shown.) so as to permit the collected materials to slide downwardly onto the delivery rollers 3.

3 represents The row of tilting plates Q0 l .bring the plates into the position shown As shown in Jthe drawings, the receiving l rollers 2 are driven by means of the sheave wheels 26, through a suitable rope drive, and the rollers 3 arranged to be driven through the bevel gears 27 and the line shaft 2S by means of any suitable motor.

In the operation of my improved apparatus, the materials are delivered on one or the otherof the sets of rollers 2 forming the receiving tables inte position alongside the hot bed to which the materials are to be transferred.

in delivering the materials on the rollers 2 of the receiving table, the hook portion 2l of the end rocking plate is in the position shown dotted in ifig. et. The rocher shaft-s 5 are then actuated to reciprocate the supports 15 and l in a vertical. direction so as to bring the series of rocking plates from the position shown dotted into that shown by full lines in Fig. Lt. lVith this movement of the rocking plates, the bar or other material on the rollers 2 is lifted therefrom and is caused to slide or roll downwardly until in engagement with the rocking plates. r)Che rocking plates are again caused to rock by the connecting mechanism so as to again dotted in Fig. 4. This movement advances the bar a further step into contact with the next set of rocking plates. Each raising and lowering movement of the plates advances the bars one step toward the opposite side of the hot bed and finally reaches the end rocking plate 17a, from which it is delivered .into the chute or slide 22.

It will be seen by reference to Figs. 5, 6, 7 and 8, that the rocking plates are arranged to overlap each other so that the bars being transferred are always in contact with each plate at a plurality of points in the length of each rocking plate and that the bar is substantially supported along its entire length while being transferred across the width of the hot bed. This is of importance, especially when very thin and flexible materials are being handled causing these materials to be transferred without buckling, kinking or damaging the edges or surfaces of such materials.

The above described operations are rel peated from time to time, as the materials are received on the receiving rollers 2, and are gradually transferred across the width of the hot bed, reaching the opposite side of the hot bed in a comparatively cold state, in

which they can be handled without liability of damage to the finished materials.

rPhe advantages of my invention will be apparent to those 'skilled in the art. The apparatus is simple, and is easily kept in repair. By means of my improved construction, a hot bed or transfer apparatus is provided which will handle materials of any cross-section, and which will deliver these materials from one side of the storage bed to the other without liability of damag(A to such materials.

rilhe materials are supported along substantially their entire length While being transferred instead of at a series of separated points as in the apparatus heretofore used for this purpose.

iModifications in the construction and arrangement of the parts may be made without departing from my invention. But one hot bed may be employed instead of the double arrangement of transfer apparatus shown; and devices for delivering the materials to and from the hot bed other than roller tables shown may be used.
